Tesla Tire Pressure Through the Seasons

Published · Last reviewed

Set each tire cold to the figure on the door-jamb placard (or in your owner manual), not to a number from a forum or a previous car. Air pressure falls as the temperature falls, so the first cold morning of autumn is when a Tesla most often shows a low-pressure warning. Check monthly and at every big temperature change, and read the result on the touchscreen to confirm it.

Why the season matters

A tire is a sealed volume of air, and air pressure follows temperature. When a cold front arrives, the same air in the same tire reads lower on a gauge. Nothing has leaked. The car notices the drop and may show a low-pressure warning, often on a cold morning that clears as the tires warm up on the road. That clearing is not an all-clear: the tire is still under-inflated when cold, and you are driving on it.

Under-inflation raises rolling resistance (so range falls), wears the tread edges faster and makes heat damage more likely on a long drive. The warning is a late signal, so a monthly gauge reading beats waiting for it.

The checking routine

  1. Park the car and let the tires cool, ideally for a few hours, before you drive more than a short distance.
  2. Find the cold tire pressure figure on the door-jamb placard, or in the owner manual if the placard is missing.
  3. Open the Service screen on the touchscreen and note the pressure shown for each tire.
  4. Compare each tire with the placard figure, then add air or release it with a gauge until it matches.
  5. Drive a short distance if the display needs to refresh, then re-read the pressures and confirm no tire warning remains.

Where to read the numbers: the placard is on the driver-side door pillar. The pressure screen is usually under Controls Service on the touchscreen, though menu names move between models and software releases, so search the manual for “tire pressure” if you cannot find it. Front and rear targets can differ on some models, so read each one.

Decisions, in priority order

Action
Inflate to the placard figure when the tires are cold, not to the higher number a warm tire reads after a drive.
Why it helps
The placard figure is a cold figure. A tire that has just been driven reads higher, and letting air out to reach the placard number leaves it under-inflated once it cools.
Verification
The gauge and the touchscreen both agree with the placard after the car has sat for a few hours.
Action
Account for where you inflate. If you add air in a warm garage and then drive into the cold, add a little extra now. A common rule of thumb is about one psi for every ten degrees Fahrenheit of difference; treat it as an estimate.
Why it helps
The tire will cool to the outdoor temperature, and the pressure will fall with it.
Verification
Re-check the next cold morning, outdoors, and adjust to the placard figure. Profile D
Action
Never exceed the maximum pressure printed on the tire sidewall, and never go below the placard figure to chase a softer ride.
Why it helps
The sidewall number is a structural limit for that tire, not a target.
Verification
Your final reading sits at the placard figure, comfortably under the sidewall maximum.
Action
Re-read all four tires after a seasonal tire swap, a rotation or a replacement, and use the figure for the tires actually fitted.
Why it helps
The placard describes the original tire size. Different tires, or a change of wheels, can have different requirements, and sensors may need attention after a swap.
Verification
The screen shows a pressure for each wheel position and no sensor error. Ask the tire shop or check the manual if one is missing.
Action
Check at the start of each season and before a long trip, and add a check whenever one tire looks lower than its neighbours.
Why it helps
A single tire that loses pressure faster than the others may have a slow puncture or a valve fault, which a seasonal drop does not explain.
Verification
All four tires lose pressure by similar amounts between checks. A repeat outlier goes to a tire shop. Profile C

If a warning appears while you are driving

Pull over somewhere safe, read the pressure screen, and look at the tires. If one is far below the others or visibly flat, do not continue on it; see the emergency kit guide.

How it works

Tire pressure is a gauge reading, meaning the amount above the surrounding air. The air inside the tire behaves like any gas: when it cools, its pressure falls; when it warms, it rises. Driving warms the tire through flexing and friction, and sun on the road warms it further, which is why a pressure taken after a drive reads higher than the same tire taken before.

That is the whole reason for the word cold. The placard figure is set for a tire that has not been driven, so it can be compared with a repeatable condition. Measuring warm gives a number you cannot interpret without correcting for the heat you added.

A Tesla reads each tire through a sensor inside the wheel and shows the result on the touchscreen. The car warns when a tire is some way below its target, so the warning protects you from a flat but not from slow, small losses. Those small losses are the ones that quietly cost range and tread. Seasonal drops happen to all four tires together, while a puncture usually shows as one tire falling away from the others, so reading all four on the same day tells you which you are dealing with.

Worked example

Suppose, purely as a hypothetical, that the placard figure for your car is 40 psi cold. On a mild afternoon at 70 °F you check the tires and find them at 40. In late October a cold snap brings an overnight low of 30 °F.

The temperature difference is 40 °F. Using the rule of thumb of about one psi per ten degrees, that is roughly a 4 psi drop, so the tires would sit near 36 psi that morning. A full physical calculation using absolute pressure gives about the same answer, which is why the rule is useful. Nothing leaked; the car may show a warning anyway.

The right response is to top each tire back up to 40 psi, measured cold, outdoors, in the morning. If you do it in a warm garage at 65 °F the same morning, you would want a little extra so the tire still reads 40 when it reaches 30 °F outside. Verify by gauge and by the touchscreen reading the next cold morning. These numbers are an illustration, not Tesla data; use your own placard.

Frequently asked questions

Why does my Tesla show a low tire pressure warning on cold mornings?

Air pressure falls as temperature falls, so tires that were fine on a warm afternoon can read low the next cold morning. The tire has not necessarily leaked, but it is still under-inflated, so add air to the placard figure.

What pressure should I use for my Tesla tires?

Use the cold figure on the door-jamb placard, or the figure in your owner manual for the tires fitted. Do not rely on a number from another car, and never exceed the maximum on the tire sidewall.

Should I check tire pressure when the tires are warm or cold?

Cold. Driving heats the tires and raises the reading, so a warm reading cannot be compared with the placard figure. Let the car sit for a few hours, or check before driving more than a short distance.

Does low tire pressure reduce a Tesla's range?

Yes, under-inflated tires have higher rolling resistance, so the car needs more energy to move. The size of the effect varies with the car and tires, so compare your own energy use before and after you correct the pressures.

How often should I check Tesla tire pressure?

Monthly, at each big change in weather, and before long trips. Reading all four tires on the same day helps you tell a seasonal drop from a slow puncture.
